Description

  The present invention relates to a mobile communication terminal device including a mobile phone, and more particularly to a mobile communication terminal device having a function of transferring electronic money.

  In a conventional mobile communication terminal device, particularly a mobile phone, a voice telephone function has been a main function. However, the usage of the e-mail has been expanding, such as e-mail capacity being expanded, data such as photographs can be attached, and browser browsing functions have become widespread.

  Recently, third-generation mobile phones using technologies such as W-CDMA have become widespread, sending and receiving e-mails with large amounts of data such as moving images, interactive video communication functions such as videophones, high-speed packets, etc. Various services such as communication functions are being developed.

  On the other hand, it has become possible to use such a diversified service. On the other hand, a user may not be aware of it and may use more communication functions than expected. is there. For this reason, a certain mobile phone service company operates a communication restriction service that sets an upper limit on the billing amount and disables communication when the upper limit is exceeded. In order to limit the use of more than necessary communication on mobile phones used by family members, especially children, etc., a function that forcibly disconnects even if trying to perform further communication is incorporated using the communication restriction service. It was.

  On the other hand, in recent mobile phones, electronic payment systems using electronic money (or electronic points) stored in an IC card or the like are becoming widespread. This system can replenish electronic money for a new amount with respect to the amount or points of electronic money stored in the IC card using, for example, a dedicated depositing terminal device. Alternatively, the IC card can be supplemented with electronic money by requesting a credit card company registered in advance using a mobile phone line. Electronic money or electronic points stored in an IC card can be used in the same way as cash at a member store of electronic money, and electronic money corresponding to the amount used is stored in a contactless IC card. For example, it is subtracted (subtracted) from the total amount. Stores where such electronic money can be used are being expanded, and services that can be used for fares of public transportation have been started, and opportunities for using electronic money are increasing.

  In the present specification, functions such as storing, replenishing, and subtracting electronic money or electronic points as described above are referred to as payment functions. The payment function is, for example, information between an ID for identifying a user, a storage unit that stores the current total amount of electronic money that changes in accordance with electronic money payment processing, and a device that performs various processes related to electronic money. And an information interface unit for exchanging information.

  Furthermore, recent mobile phones are equipped with positioning means using a GPS function or the like so that the current position of the mobile phone can be specified in an emergency. This positioning function is used not only for the purpose of identifying the current location of the caller in the case of an emergency call, but also for the purpose of the user confirming the current location, the purpose of the second party confirming the user's location, and the like. The function to confirm the user's position can be specified when a child is involved in troubles such as kidnapping, so mobile phones for children have also been developed. Parents carry such mobile phones to their children. Opportunities to have telephones are increasing. From the above trend, it is assumed that many children use mobile phones, and electronic money can be used in the mobile phones. As an electronic money management method, there is a technique using a management method described in Patent Document 1 below.

JP 2004-102726 A.

  However, since the management means described in Patent Document 1 adds and manages information specifying the purpose of use to electronic money, the parent cannot be involved except for the given electronic money. For example, it is possible to receive electronic money from another person's mobile phone, and if the child can freely use the electronic money received in this way, he / she can receive more electronic money than the parent imagines. It may be used. In addition, when electronic money is transmitted as a normal pocket money, its usage is not specified, so it is possible to lend and borrow electronic money with friends. Furthermore, electronic money can be received from someone other than the parent. There is a problem that the electronic money received in this way or the electronic money supplemented to the mobile phone itself can be lent and borrowed with friends as in the previous example.

  Further, no special processing is performed on the side for giving electronic money when setting the transmission destination. There is no problem as long as it is a means of performing direct one-to-one communication using terminals such as infrared communication, but in the case of award using communication by radio waves of a mobile phone, electronic money is erroneously transmitted. There is also a possibility that electronic money is transmitted to a mobile phone other than the child who is the transmission partner. Furthermore, by attaching information specifying the purpose of use to electronic money, for example, electronic money for purchasing stationery, electronic money for purchasing medicine, electronic money for purchasing food, etc. are managed for each purpose of use. As a result, there is a problem that the management of the balance of electronic money becomes complicated.

  The present invention solves the above-described problems in a method for replenishing a contactless IC card with electronic money or replenishing a prepaid subscriber identification module with a prepaid call charge, and provides a user-friendly device. For the purpose.

  According to one aspect of the present invention, a data communication unit that performs data communication, a first IC card that has an interface related to electronic money and a payment function using electronic money, and a second that stores information necessary for data communication. An IC card, and a mobile device mode that operates as a parent device mode for sending electronic money or receives electronic money based on mode information stored in the second IC card An operation mode determination unit that determines whether to operate as an electronic money, and an electronic money processing unit that performs processing related to transmission / reception of electronic money via the data communication unit based on the determination of the operation mode determination unit A portable communication terminal device is provided.

  According to the above configuration, another route is provided via the first IC card and the interface related to electronic money, and the electronic money is replenished from the parent device to the child device by a route different from general electronic money exchange. This makes it possible to replenish electronic money safely.

  When the operation mode determination unit determines that the operation mode determination unit is in the parent device mode, the electronic money processing unit transmits the data to the transmission destination selected based on the child device data information stored in the second IC card. When it is determined that the electronic money is transmitted from the communication unit and operates in the slave mode, it is preferable that only the electronic money transmitted from the parent device is permitted to be supplemented to the first IC card. Depending on whether the parent device mode or the child device mode, the processing related to the compensation of electronic money can be changed, and only replenishment of electronic money from the parent device to the child device can be permitted.

  It is also possible to have a call charge compensation unit that adds the received electronic money to the prepaid data of the second IC card and makes it available as a prepaid call charge. Thereby, in the slave unit, the electronic money compensated from the master unit can be compensated for the call charge. In this case, the use of the money in the handset is restricted by adding an identification ID such that the electronic money replenished from the base phone is covered only by the call charge, the call charge can be covered, and the call charge cannot be covered. You can also As a function of the mobile phone, it is assumed that electronic money can be supplemented to both the parent device and the child device. For this reason, it is a point of the present application to provide a restriction so that the electronic money given to the child device by the parent device as a call charge is not used as electronic money on the child device side. Furthermore, it has a transfer function for transferring electronic money stored as the prepaid data to the second IC card with respect to the first IC card.

The present invention also provides a data communication unit for performing data communication, a first IC card having an interface related to electronic money and a payment function using electronic money, and a second IC card for storing information necessary for data communication. , And operates as a parent device mode for sending electronic money or as a child device mode for receiving electronic money based on mode information stored in the second IC card The mobile communication terminal device includes an operation mode determination unit that determines whether or not, and an electronic money processing unit that performs processing related to payment of electronic money based on the determination of the operation mode determination unit.
In this way, it is possible to use another route for settlement of electronic money.

  According to another aspect of the present invention, a data communication unit that performs data communication, a first IC card that has an interface related to electronic money and a payment function using electronic money, and a second that stores information necessary for data communication. A method of processing electronic money in a mobile communication terminal device that operates by being inserted, comprising: a master unit that sends electronic money based on mode information stored in advance in the second IC card An operation mode determination step for determining whether to operate as a mode or a slave device mode for receiving electronic money, and an electronic money for performing processing related to transmission / reception of electronic money based on the determination in the operation mode determination step And a processing step. An electronic money processing method in a mobile communication terminal device is provided.

  Furthermore, a mobile phone comprising: a data communication unit that performs data communication; a first IC card that has an electronic money interface and a payment function using electronic money; and a second IC card that stores information necessary for data communication A method for processing electronic money in a communication terminal device, which operates as a parent device mode for sending electronic money or a child device mode for receiving electronic money based on mode information stored in the second IC card An electronic device in a mobile communication terminal device, comprising: an operation mode determination step for determining whether to operate; and an electronic money processing step for performing processing related to settlement of electronic money based on the determination in the operation mode determination step A method for processing money is provided.

  According to the present invention, since transmission is permitted based on the information of the slave unit stored in the second card, the possibility of erroneous transmission of electronic money to an unexpected partner when transmitting from the master unit side is reduced. it can.

  In addition, in the slave unit, reception of electronic money is permitted only when it matches the information of the master unit stored in the second card, and in the slave unit, electronic money from other than the master unit is not compensated. The possibility of receiving electronic money from others is reduced. Furthermore, since it becomes a mechanism which cannot transmit electronic money in a subunit | mobile_unit, it becomes impossible to share electronic money to others.

  In order to eliminate the troublesome management of electronic money by a child, it is possible to carry out settlement of electronic money through the parent device. As a result, a child using a handset can use electronic money in a mobile phone without being aware of the purpose of use. Can be purchased using the electronic money of the parent machine.

  Furthermore, since it is stored as data inside the second card whether or not it is a slave unit, when used in a mobile phone or the like, there is no need for the service provider to be the same mobile phone provider in particular. In addition, electronic money can be transmitted and received between terminals between different providers. Furthermore, when the base phone and handset are set to UICC, a special setting is made to the mobile phone terminal when, for example, a third-generation mobile phone or a mobile phone terminal into which UICC is inserted such as GSM is replaced. Therefore, even when a mobile phone terminal is directly purchased from a mobile phone manufacturer, it is possible to continue using this function without performing special settings.

  There are the following technologies as basic technologies related to payment technology using electronic money for mobile phones. That is, an IC card module suitable for a mobile communication system represented by a USIM conforming to the plug-in UICC standard or a compatible third-generation mobile phone is common to different types of phones. By replacing the IC card module and using it, the telephone number and billing information can be used as they are. This type of card substrate is 15 mm × 25 mm × as in the SIM card, as in the plug-in UICC standard in ETSI TS (European Telecommunications Standardization Institute TechnICal SpecifICation) 102 221 V4.4.0 (2001-10). The external interface terminals of the microcomputer are arranged in a relatively large pattern conforming to the ISO / IEC 7816-2 terminal position and function standards. A unique number called IMSI (International Mobile Subscriber Identity) is assigned to the USIM card, and communication is possible by connecting this number to a telephone number. By inserting / removing the USIM card, the telephone number can be transferred to another mobile phone, or a plurality of telephone numbers can be switched and used by one mobile phone. The UICC card described below is an example, and other cards can be applied.

  On the other hand, the following non-contact IC card unit is a card on which an IC chip that can be mounted on a mobile phone is mounted, and has a communication / authentication function. By using this function, corresponding services such as electronic money and electronic tickets can be used. By holding the mobile phone over a reader in a non-contact state such as a register, electronic money can be exchanged and electronic payment processing can be performed quickly.

  The parent device refers to a terminal that can transmit electronic money, and the child device refers to a terminal that has only a function of receiving electronic money transmitted from the parent device. Note that the slave unit may have a function of requesting the master unit to transmit electronic money.

  The interface related to electronic money refers to an interface for exchanging electronic money with, for example, a vending machine capable of selling products and the like with electronic money.

  Hereinafter, a mobile terminal device according to an embodiment of the present invention will be described with reference to the drawings, taking a mobile phone as an example.

  FIG. 1 is a functional block diagram showing a configuration example of a mobile phone according to an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes an antenna of a mobile phone radio unit. Reference numeral 2 denotes an RF unit, 3 denotes a baseband unit, 4 denotes a control unit, and 5 denotes an example of a card inserted into the mobile phone and used. A UICC card, 6 is an LCD display unit, 7 is an operation unit such as a button key, 8 is a non-contact type IC card unit, and 9 is an antenna unit used for the non-contact type IC card.

  Communication of the mobile phone according to the present embodiment is performed via the antenna 1, the RF unit 2, and the baseband unit 3. In addition, the control unit 4 includes a data processing unit 401 that processes transmission / reception data, a mode determination unit 402 that determines whether the mobile phone operates as a parent device or a child device, and deposits and transfers of electronic money. An electronic money processing unit 403 that performs the above processing, a call charge compensation unit 404 that compensates the electronic money of the contactless IC card with prepaid data of UICC, and when the mobile phone is operating as a slave unit, An electronic money requesting unit 405 that makes a request for money settlement processing, and a purchase information acquisition unit 406 that acquires information about a product or service to be purchased with electronic money from the non-contact IC card unit 8 are included.

  On the other hand, in a memory (not shown) of the UICC card 5, mode information 501 indicating whether the parent mode or the child mode is set, and when the UICC is set to the parent mode, the telephone number of the child mode is recorded and set to the child mode. If the telephone number of the parent mode is recorded, the telephone number (1) information 502, the telephone number (2) information 503, and prepaid data 510 in which prepaid communication costs are recorded are stored as information. Yes.

  The control unit 4 controls the overall processing of the mobile phone, and is connected to the baseband unit 3, the display unit 6, the operation unit 7, the UICC card 5, and the non-contact IC card unit 8 so that each can be controlled. It is configured.

  Although not shown in the figure, mobile phones have recently been equipped with various functions such as a GPS function, a digital TV reception function, and a music playback function. Done. The mode discriminating unit 402 acquires the mode information 501 stored in the UICC card 5 and discriminates whether to operate as the parent device mode or the child device mode. The control unit 4 performs control related to electronic money according to the determination result of the mode determination unit 402. The data processing unit 401 performs processing related to packet data transmission / reception. A radio signal received by the antenna 1 of the mobile phone is converted into a baseband signal by the RF unit 2 and demodulated by the baseband unit 3. The demodulated data is transferred to the data processing unit 401 of the control unit 4, and it is determined whether the data is data related to electronic money or normal data such as a browser or e-mail. When the demodulated data is data related to electronic money, the demodulated data is transmitted to the electronic money processing unit 403.

  The electronic money processing unit 403 checks whether or not the transmission source of the received electronic money matches the parent mode telephone number (1) information 502 or telephone number (2) information 503 recorded in the UICC card 5. When both telephone numbers match, the display unit 6 displays that the electronic money data has been received, so that the electronic money is deposited into the UICC card 5 or the electronic money is input into the non-contact IC card unit 8. Prompt the user to determine whether to

  In accordance with the displayed menu, the user uses the operation unit 7 to determine the storage location of the electronic money. When the storage destination selected using the operation unit 7 is a call charge supplement, that is, when saving to the UICC card 5 is selected, the electronic money processing unit 403 compensates the electronic money information for the call charge. To the unit 404. The call charge compensation unit 404 converts the received electronic money into call charge prepaid data, and adds it to the prepaid data information 510 set in the UICC card 5. The added electronic money can be used for calling charges, packet communication charges, and the like thereafter. When the electronic money storage destination selected using the operation unit 7 is a non-contact IC card, it is stored in the non-contact IC card unit 8. Electronic money stored in the non-contact IC card 8 can be exchanged with store terminals, vending machines, etc. via an antenna 9 for electronic commerce.

  The phone number (1) 502 and the phone number (2) 503 stored in the UICC card 5 are also used when electronic money is sent from the parent device to the child device. When the electronic money transmission process is executed by the control unit 4, the mode determined by the mode determination unit 402 is confirmed. When the operation mode is the slave mode, the electronic money processing unit 403 rejects the electronic money sending process. At this time, a message to the user is displayed on the display unit 6, for example, “This mobile phone is in a handset mode, so electronic money cannot be sent”, and the process is terminated.

  When the discrimination result in the mode discrimination unit 402 is “master mode”, the phone number of the slave that can be transmitted is acquired from the phone number information (1) 502 and the phone number information (2) 503 of the UICC card. . The telephone number information (1) 502 and the telephone number information (2) 503 are candidates for the number of the slave unit if it is a master unit, and the master unit number if it is a slave unit. The number is arbitrary. For example, the child machine may contain four numbers of parents and grandparents, or in the case of the parent machine, for example, the number of two children may be entered.

  The telephone number information is displayed on the display unit 6, for example, and prompts the user to select a destination. On the other hand, when the user selects a desired telephone number using the operation unit 7, the electronic money processing unit 403 performs electronic money sending processing to a destination specified by the telephone number.

  The operation of the handset that has received this electronic money is as described above. Although two telephone numbers are described as being settable in this embodiment, the number that can be set is not limited to two. As for the communication function, any method such as PDC, W-CDMA, OFDM, etc. can be used. When transferring data by PPP communication or the like, a mail address is set in the terminal instead of the phone book. It is also possible. That is, in the above description, the example in which the other party is specified by the telephone number has been described. However, the same processing can be performed even if the destination is replaced with an e-mail address or the like.

  The electronic money request unit 405 and the purchase information acquisition unit 406, when a terminal operating in the slave mode performs settlement of electronic money using a terminal operating in the master mode, that is, the electronic money of the master terminal of the own terminal Used for. When the user using the terminal in the slave mode wants to settle the account using the electronic money of the master unit, the electronic money request unit 405 requests the purchase information acquisition unit 406 to acquire purchase information. In response to this request, the purchase information acquisition unit 406 requests the contactless IC card unit 8 to acquire purchase information. The non-contact IC card unit 8 acquires information related to purchase through an electronic commerce system. The information regarding purchase includes, for example, a store name, a product name, and a product price. Information regarding the purchase is sent to the electronic money request unit 405. When the electronic money request unit 405 prompts the data processing unit 401 to transmit an electronic money request, data regarding the electronic money request is transmitted as a wireless signal of the mobile phone via the baseband unit 3, the RF unit 2, and the antenna 1. The request is sent to the parent device for electronic money.

  FIG. 2 is a flowchart showing the flow of electronic money transmission processing according to this embodiment. Here, the mobile phone is in a normal standby state, and the display unit 6 is in a state where a standby screen or the like is displayed (step S1). When menu display is selected on the operation unit 7, the main menu is displayed (step S2). The configuration of the main menu and the sub menu is arbitrary, and the configuration differs depending on the terminal, but the electronic money selection menu is displayed by the user's selection operation. If the electronic money menu is not selected, the selected process is executed (other selection, step S5).

  When the electronic money menu is selected, a selection menu of 1) display indicating transfer to prepaid telephone charge and 2) display indicating transmission to the slave unit is displayed, prompting the user to input (step S4). When the transfer to the prepaid telephone charge of 1) is selected (UICC selection), the transfer process to the UICC is executed below.

  As a transfer process to the UICC, a password authentication process is first performed in order to avoid unauthorized use by others. When the user inputs a password (step S6), the verification is performed (step S7). If the passwords do not match (No), it is confirmed whether the number of times of input is equal to or less than the specified number (step S11). If it is less than the specified number of times (No), the screen again returns to the password input screen (step S6) and prompts for the password input. If the specified number has been exceeded (Yes), a password error is displayed (step S12), and the screen returns to the main menu screen or standby screen (step S2). If the password is incorrect after exceeding the specified number of times, processing relating to electronic money cannot be executed thereafter.

  If the passwords match (Yes), the screen continues to enter the transfer amount input screen. When the user inputs an amount (step S8), a confirmation process is performed as to whether or not the amount can be transferred (step S9). For example, as a result of confirmation, if the input amount exceeds the amount of electronic money supplemented to the IC card (No), a warning message is displayed (step S13), and the initial screen (main menu or standby screen) ). If there is no problem with the input amount (Yes), the electronic money processing unit 403 (FIG. 1) acquires the value of the prepaid data 510 of UICC. The input amount is added to the acquired value, and the addition result is overwritten on the prepaid data 510. Further, the balance of the non-contact IC card is updated by subtracting the amount of electronic money input from the amount of electronic money stored in the non-contact IC card unit 8 (step S10). After the update, the screen transitions to a normal screen (standby screen), and after that, the normal mobile phone can operate.

  If the transfer to the child device is selected in the transfer of electronic money in step S4, first the UICC card mode is checked (step S14). Since electronic money can be transferred only in the parent device mode, if the mode is the child device mode in the determination processing in step S15 (No), for example, that fact is displayed on the display unit 6 and processing is performed. Exit. Thereafter, the normal operation is performed. If the mode information 501 of the UICC card 5 is set to the master mode (Yes), the user is prompted to enter a password for security (step S16). If the password is incorrect in step S17 (No), the screen returns to the password input screen again to prompt for the password. If the specified number has been exceeded (step S24), a password error is displayed (step S25), and the screen returns to the main menu screen or the standby screen. If the password is incorrect after exceeding the specified number of times, processing relating to electronic money cannot be executed thereafter.

  If the passwords match (Yes in step S17), the screen proceeds to an input screen for the amount to be transferred. If the passwords match, the screen transits to the transfer destination confirmation screen (step S18). In this embodiment, the number of transfer destinations is not limited to one, and it is possible to set a plurality of child devices. For example, two telephone numbers are set as the telephone numbers of the slave units, and the telephone number (1) 502 and the telephone number (2) 503 are stored in the UICC. The electronic money processing unit 402 obtains this value from the UICC, and displays it on the display unit 6 via the control unit 4 to check whether the transfer destination is permitted (step S19). (No) Returning to step S2, if permitted, the user is prompted to select a telephone number. The control unit 4 uses the operation unit 7 to send electronic money to the slave unit selected by the user using the communication means (step S20).

  After sending, transition to normal operation (standby screen). After the electronic money is transmitted, the mobile device is in a state of waiting for confirmation of the response from the slave unit. If the reception processing of the electronic money is correctly performed in the slave unit, a message indicating that the electronic money has been normally received is returned from the slave unit to the master unit (step S21).

  When the master device receives this result, the transmission processing for all electronic money is completed (Yes in step S22, step S23). If the electronic money is not normally processed in the child device (No in step S22), an error notification is transmitted to the parent device. When the parent device receives the error notification, it is determined that the electronic money has not been correctly transmitted to the child device, and electronic money return processing is performed. In this case, all the electronic money transmission processing is not performed, and the result is the same as when the electronic money is not transmitted / received between the parent device / the child device (steps S26 and S27).

  Next, the flow of processing when electronic money is received will be described with reference to FIG. 3 and FIG. In step S31, processing is started (start), and when packet data is received (step S32), the data processing unit 401 determines whether the data relates to electronic money or other general communication (e-mail, etc.). It is judged whether it is a thing (step S33). The data format of electronic money is not particularly limited as long as the data can be confirmed as electronic money data in each of the parent device on the transmission side and the child device on the reception side.

  If the data is not electronic money data (No), the packet data becomes normal packet data, and processing corresponding to the data, for example, mail reception processing is performed. If the received data is electronic money data (Yes), the base unit number is confirmed (step S34), and if the base unit number is confirmed (Yes), it is confirmed that the display unit 6 has received the electronic money. Display and prompt the user for confirmation. When the user confirms (for example, a message indicating electronic money reception is displayed on the pop-up screen and the “OK” key in the pop-up screen is pressed), a password input screen for security is displayed on the display unit 6 ( Step S35). The user inputs the password (step S36), and the control unit 4 checks whether the passwords match (step S37).

  If the password is incorrect (No), it is confirmed whether the password has reached the specified number of times (step S44). When the specified number of times has not been reached (No), the screen changes again to the password input screen (step S36). If incorrect passwords are continuously input and the number of times of input exceeds the specified number (Yes), a message indicating a password error is displayed on the display unit 6 (step S45), and the process is terminated. If a password error occurs, processing of electronic money is not permitted afterwards for security. With respect to operations other than electronic money, there is no particular restriction, and after completion, transition to normal operation (standby screen).

  If the passwords match on the password input screen (Yes), the screen changes to the transfer destination selection screen. Two forwarding destinations, call charge supplement and electronic money supplement, can be selected (step S38). When the call charge supplement is selected, the received electronic money is stored in the UICC card 5. The prepaid data 510 is read out by the electronic money processing unit, the amount of the received electronic money is added to this value, and the prepaid data 510 is overwritten again. When the IC card is selected, the remaining amount of the non-contact IC card is confirmed, the amount of the received electronic money is added to the remaining amount, and the remaining amount of the non-contact IC card is updated (step S42). In both cases of electronic money balance compensation and transfer to UICC, it is confirmed whether or not it has been completed normally. When the electronic money transfer process is normally completed (Yes in step S39), a message indicating normal completion is transmitted to the parent device (step S41). If an abnormality occurs and electronic money cannot be compensated or registered as a prepaid fee for UICC, a message indicating the abnormality is transmitted to the parent device (step S43). On the base unit side, the electronic money is restored by this message as described above.

  A typical embodiment of the present invention has been described above, but the communication means is not particularly limited as long as it can transfer packet data such as PDC, W-CDMA, OFDM, and wireless LAN. The number of slave units may be one or more, and the slave unit information may be an email address, an IP address, or a combination of the data instead of a telephone number. Furthermore, although the slave unit information displayed on the master unit is not shown in the figure, it is checked against the data in the phone book, and if there is a phone number, e-mail address, or IP address that matches the phone book, that phone book The registered name can be displayed on the display unit.

  Next, the flow of processing for performing electronic money settlement in the parent device will be described. FIG. 4 is a processing flow relating to the operation on the child device side, and FIG. 5 is a processing flow relating to the operation on the parent device side.

  In FIG. 4, at the start time (step S51), it is assumed that an operation menu related to the mobile phone is displayed on the display unit 6 (step S52). Therefore, it is confirmed whether or not an electronic money request (financial settlement processing at the parent device) is selected (step S53). If the settlement request to the parent machine is not selected and the other process is selected, the selected process is executed and the process ends (step S55). If the settlement request at the parent device is selected, it is confirmed at step S54 whether or not it is in the child device mode. If it is the master mode (No), since the master unit mode is displayed on the display unit 6, it is displayed that this process cannot be executed, the user is warned, and the process is terminated. If it is the slave mode (Yes), purchase information is acquired (step S56).

  As described above, this information is obtained from a non-contact IC card through an electronic settlement system, and includes store information, product name, price, quantity, and the like. In addition, the address of the store, the type of product such as stationery, sweets, and toys may be included. When the purchase information is acquired, a transfer destination selection display is performed on the display unit 6. It is confirmed whether or not the selected transfer destination matches the telephone number (1) 502 or the telephone number (2) information 503 stored in the UICC card 5 (steps S56 and S57). If they do not match (No in step S58), the display unit 6 displays that the transfer destination is not permitted, and the process ends. If it matches the telephone number (1) information 502 or the telephone number (2) information 503 stored in the UICC card 5 (step S58), the purchase information is transmitted to the transfer destination (master unit). After the purchase information is transmitted, it waits as a result of whether or not the request is permitted in the parent device. Until the permission information is transmitted from the parent device, no special processing is performed until the permission information is received. When the permission information is entered (step S59), it is confirmed whether or not the purchase is permitted (step S60). If not permitted (No), the display unit 6 notifies the user that the purchase is not permitted by the parent machine, and the process is completed.

  If permitted, the electronic commerce is completed via the non-contact IC card unit 8 using the electronic money received simultaneously with the permission information (steps S62 and S63).

  On the base unit side, the function of the mobile phone or the function attached to the mobile phone is operating, but when data relating to the electronic money request is acquired, the processing is performed according to the procedure shown in FIG. First, when a request for electronic money is received (steps S71 and S72), it is confirmed whether or not it is a parent device mode (step S73). If it is the handset mode (No), there is no electronic money settlement authority, and the process is terminated. If it can be confirmed that it is the parent device mode (Yes), it is confirmed whether the information is from the registered child device. It is confirmed whether the telephone number information sent from the request matches the telephone number (1) information 502 or the telephone number (2) information 503 of the UICC card 5 (step S74). If they do not match (No), it is determined that the request is invalid and the process is terminated.

  If they match (Yes), it is determined that there is a request for electronic money settlement, and purchase information is displayed. The display unit 6 displays purchase information and a permission / non-permission selection screen. The user of the parent machine confirms the purchase information, and selects “permitted” if it can be permitted, or “denied” if it is determined that the purchase is unnecessary (step S76). The selected result is transmitted to the child device (step S77). If permitted, the permission information is transmitted, and the electronic money information necessary for purchase is also transmitted to the child device. If it is denied, electronic money is not transmitted. The sent approval information is processed in the slave unit as described above (step S78). As described above, according to the mobile terminal device according to the present embodiment, since transmission is permitted based on the information of the slave unit stored in the UICC card, when transmitting from the base unit side, an unexpected partner No electronic money is sent to the user. Also, in the slave unit, reception of electronic money is permitted only when the information matches the master unit information stored in the UICC, and in the slave unit, electronic money from other than the master unit is not compensated. You won't receive electronic money. Furthermore, since it becomes a mechanism which cannot transmit electronic money in a subunit | mobile_unit, it cannot distribute electronic money to others. Therefore, it is possible for the child to carry out the settlement of electronic money via the parent machine in order to eliminate the troublesome management of electronic money. As a result, a child using a handset can use electronic money in a mobile phone without being aware of the purpose of use. In addition, for products whose use is limited, the parent's consent with electronic money. It is also possible to purchase using the electronic money of the parent machine.

  In addition, since it is stored as UICC internal data whether or not it is a slave unit, when used in a mobile phone or the like, it is not particularly necessary for the service provider to be the same mobile phone provider, between different operators It is also possible to send and receive electronic money between terminals. Further, the settings of the master unit and the slave unit are set to UICC. Therefore, for example, when purchasing a mobile phone terminal that inserts UICC, such as a third-generation mobile phone or GSM, it can be used without special settings for the mobile phone terminal, and even when the mobile phone terminal is purchased directly from the manufacturer. There is an advantage that the electronic money settlement function can be used continuously without any special setting.

  The present invention can be used for settlement of electronic money using a mobile terminal device.
